As part of the company's ongoing energy efficiency program, 3300 Irvine Avenue, constructed in 1981, was chosen as a candidate for a lighting retrofit. The retrofit consists of replacing the existing F-40 lamps with high efficiency T-8 lamps, installing energy efficient ballasts and occupancy sensors. This retrofit was completed in 1999.

In a continuing effort to reduce operating costs, optimum start and stop times have resulted in a further reduction of energy.
